Data from: Spatially correlated extinctions select for less emigration but larger dispersal distances in the spider mite Tetranychus urticae

Emanuel A. Fronhofer, Jonas M. Stelz, Eva Lutz, Hans Joachim Poethke & Dries Bonte
Dispersal is a central process to almost all species on earth, as it connects spatially structured populations and thereby increases population persistence. Dispersal is subject to (rapid) evolution and local patch extinctions are an important selective force in this context. In contrast to the randomly distributed local extinctions considered in most theoretical studies, habitat fragmentation or other anthropogenic interventions will lead to spatially correlated extinction patterns. Under such conditions natural selection is thought to lead...

Data from: Specialization and phenological synchrony of plant–pollinator interactions along an altitudinal gradient

Gita Benadi, Thomas Hovestadt, Hans-Joachim Poethke & Nico Blüthgen
1. One of the most noticeable effects of anthropogenic climate change is the shift in timing of seasonal events towards earlier occurrence. The high degree of variation in species' phenological shifts has raised concerns about the temporal decoupling of interspecific interactions, but the extent and implications of this effect are largely unknown. In the case of plant–pollinator systems, more specialized species are predicted to be particularly threatened by phenological decoupling, since they are assumed to...

Data from: Prevention of ventilator-associated pneumonia in intensive care units: an international online survey

Background: On average 7% of patients admitted to intensive-care units (ICUs) suffer from a potentially preventable ventilator-associated pneumonia (VAP). Our objective was to survey attitudes and practices of ICUs doctors in the field of VAP prevention. Methods: A questionnaire was made available online in 6 languages from April, 1st to September 1st, 2012 and disseminated through international and national ICU societies. We investigated reported practices as regards (1) established clinical guidelines for VAP prevention, and...

Data from: Rapid evolution of larval life history, adult immune function and flight muscles in a poleward moving damselfly

Lieven Therry, Viktor Nilsson-Örtman, Dries Bonte & Robby Stoks
Although a growing number of studies have documented the evolution of adult dispersal-related traits at the range edge of poleward-expanding species, we know little about evolutionary changes in immune function or traits expressed by nondispersing larvae. We investigated differentiation in larval (growth and development) and adult traits (immune function and flight-related traits) between replicated core and edge populations of the poleward-moving damselfly Coenagrion scitulum. These traits were measured on individuals reared in a common garden...

Data from: Sex-biased dispersal at different geographical scales in a cooperative breeder from fragmented rainforest

Carl Vangestel, Tom Callens, Viki Vandomme & Luc Lens
Dispersal affects both social behavior and population structure and is therefore a key determinant of long-term population persistence. However, dispersal strategies and responses to spatial habitat alteration may differ between sexes. Here we analyzed spatial and temporal variation in ten polymorphic microsatellite DNA loci of male and female Cabanis’s greenbuls (Phyllastrephus cabanisi), a cooperative breeder of Afrotropical rainforest, to quantify rates of gene flow and fine-grained genetic structuring within and among fragmented populations. We found...

Data from: Rapid range expansion increases genetic differentiation while causing limited reduction in genetic diversity in a damselfly

Janne Swaegers, Joachim Mergeay, Lieven Therry, Maarten H. D. Larmuseau, Dries Bonte & Robby Stoks
Many ectothermic species are currently expanding their geographic range due to global warming. This can modify the population genetic diversity and structure of these species because of genetic drift during the colonization of new areas. Although the genetic signatures of historical range expansions have been investigated in an array of species, the genetic consequences of natural, contemporary range expansions have received little attention, with the only studies available focusing on range expansions along a narrow...
